Audio Compressor

The Audio Compressor is a dedicated online tool for compressing the dynamic range (the difference between loud and quiet parts) of your audio files. Using the DynamicsCompressorNode, it automatically attenuates volume that exceeds the set threshold, producing a consistent and easy-to-listen sound.

Whether you want to even out vocal volume, add punch to drums, increase overall loudness for mastering, or achieve uniform volume for broadcast, this tool handles it all. With 5 carefully curated presets (Vocal, Drums, Mastering, Broadcast, and Gentle), beginners can use it easily, while custom mode allows professional fine-tuning with six parameters: threshold, ratio, attack, release, knee, and makeup gain.

Each parameter features helpful tooltips on hover to guide your adjustments. Custom settings are automatically saved to your browser, allowing you to restore your previous configuration on your next visit. All processing runs via Web Audio API in the browser, so your audio data is never sent to a server, ensuring complete privacy protection. Export your compressed audio as MP3 or WAV, giving you flexibility in choosing the format that best suits your needs.
